VIENNA, July 13 --

- Attitudinal and Behavioural Barriers(1) - Combined with Inability to
Recognize Disease Symptoms(1) - Contribute to Delay in Diagnosis and Treatment

A new study presented today at a major International medical meeting reveals
that approximately two-thirds of physicians in the United Kingdom, France,
Italy, Spain and Germany agree that Alzheimer’s disease (AD) is
under-diagnosed(1) and under-treated,(1) and explains how physicians, carers and
the general population share responsibility in the issue. Based on these
results, the Steering Committee overseeing the study recommends the development
of programmes to help physicians meet the specific challenges associated with
diagnosing such a devastating disease, and educational tools for physicians and
the general population to help them spot the early signs of AD.

According to the study, which was presented at the 2009 Alzheimer’s
Association International Conference on Alzheimer’s Disease (ICAD 2009)
and sponsored by Eisai and Pfizer Inc, physicians who feel AD is under-diagnosed
believe this can be explained by:

- Physician uncertainty in discussing the early stages of AD (76 percent)(1) -
Family tendency to ignore (79 percent)(1) or not watch for (90 percent)(1) the
early symptoms - An apathetic ’what’s the point?’ attitude, as
57 percent of physicians(1) agreed that there is little to gain from diagnosis,
as there are no effective treatments - Emotional barriers making it
uncomfortable for physicians to deliver bad news (54 percent)(1)

These beliefs exist despite the fact that 74 percent of physicians(1) and 63
percent of carers(1) agree that early treatment delays the progression of
disease symptoms in some patients. The Steering Committee concluded that such
attitudes and behaviours prevalent across Europe may have a negative impact on
AD patients’ and carers’ quality of life and ability to benefit from
timely diagnosis. Prompt diagnosis has several advantages, including the
opportunity to start treatment, which can delay decline in ability to perform
day-to-day activities,(3) decrease carer burden(4) and stress,(5) and delay
patient admission to long-term care institutions.(6) Addressing the disease
without delay also provides more time for a person with AD and their family to
adjust to the news, join support organisations and plan for the future,
financially and emotionally.(7)

Undoubtedly external political and social factors which vary from country to
country, including government resources, cost and treatment restrictions, take
their toll on diagnosis and treatment rates. However, this study brings to light
attitudinal and behavioural factors within our control that may be just as
important barriers to effective management of this devastating disease, the most
common form of dementia, which is due to rise by approximately 70 percent by the
year 2040, affecting 10 million people in Europe, said Professor Roy Jones,
Clinical Gerontologist and Geriatrician at The Research Institute for the Care
of Older People, Bath, and Study Steering Committee Chair.

Need for Increased Awareness of Early AD Symptoms - Among Physicians and the
General Public

Additional results of the Important Perspectives on Alzheimer’s Care
Treatment, or IMPACT study, highlight an agreement that many people would not be
able to recognize the early signs of AD,(1) or be able to tell the difference
between AD and normal ageing.(1) This is reinforced by the finding that carers
waited an average of 10 months to call a physician after noticing the signs of
disease.(1) Across all respondents, a majority also feel that general
practitioners (vs. specialists) have a difficult time detecting the early stages
of AD.(1) This delay in seeking a physician’s advice, and lack of
awareness of the early signs, may place future patients and their families at a
potential disadvantage in securing the benefits of timely diagnosis and
treatment.(7) As the incidence of AD continues to rise across Europe,(8) anyone
could be in the position to identify signs of AD in someone they love in the

Whilst carers and physicians alike know that early treatment delays the
progression of disease symptoms, almost a year goes by before carers call
physicians, who themselves may then be too inexperienced, uncertain or otherwise
emotionally unable to deliver timely diagnosis and treatment. Detecting the
early signs of the disease is challenging for everyone, but we need to move
people away from fear, denial and hesitation, so that physicians and the general
population - our future carers - can increase their knowledge of AD, and put
that knowledge into action, said Professor Pablo Martinez-Lage, Neurologist at
the Institut Catala de Neurociencies Aplicades, Barcelona, and member of the
IMPACT Study Steering Committee.

Desire to Know Outweighs Fear of Disease and its Impact on Families

IMPACT also suggests that the physicians’ perception of the impact of AD
on the family may be greater than that of the carers. Approximately nine out of
ten physicians agree that AD has a devastating effect on a family,(1) but
significantly fewer carers (75 percent)(1) feel that way. Further, although the
study shows AD carers are the only respondents to fear AD more than cancer,(1)
they would still want to know as soon as possible if they(1) or a family member
had the disease.(1)

Marc Wortmann, Executive Director of Alzheimer’s Disease International
and member of the IMPACT Study Steering Committee, said, We have found through
IMPACT that fear does not overwhelm the carer desire to find out about
Alzheimer’s disease as early as possible. Perhaps physicians underestimate
this desire to know because of their unique knowledge of the path ahead and
’over concern’ about the impact of a diagnosis. We need to act now
to address the unique obstacles facing physicians, carers and the general
population, and tackle the barriers influencing how people feel and act when it
comes to Alzheimer’s disease. How we choose to react to today’s
challenges will determine our ability to best support the rising numbers of
tomorrow’s patients and carers. Many health systems in the world are not
ready for this challenge.

About Alzheimer’s Disease

Alzheimer’s disease, a progressive and degenerative brain disease,(9) is
the most common type of dementia.(9) Dementia affects more than 30 million
people worldwide(10) including more than six million Europeans.(8) Symptoms of
AD may include increased forgetfulness, repeating or asking the same question
frequently, and problems making decisions.(11) These symptoms gradually affect a
person’s cognition, behavior and everyday activities, some severe enough
to have an impact on their work, social activities and family life.(11) While
there is no cure for AD, there are treatments to help slow the progression of
the symptoms of the disease.(12)

About the IMPACT Study

The IMPACT study was conducted online within the United Kingdom, France, Italy,
Spain and Germany by IPSOS on behalf of Eisai and Pfizer Inc, between April 1
and May 1, 2009, among 500 physicians (including general practitioners and
specialists), 250 AD carers, 50 payors and 1,000 members of the general
population age 18 and over. Statistical differences are noted using a 90 percent
confidence interval. A full methodology is available upon request.

About the IMPACT Study Steering Committee

The IMPACT study was developed and implemented with the oversight of an expert
Steering Committee comprised of a variety of leading AD specialists, including
geriatricians, neurologists, epidemiologists, primary care physicians, old-age
psychiatrists and advocacy leaders from the United Kingdom, France, Italy, Spain
and Germany. The Committee was sponsored by Eisai and Pfizer Inc.
